Most important by far: you care about the success of others more than you care about your own success. Everyone around you needs to ultimately become better than you.
That’s how you lead. The light is in front of you and you take them to the light and then go back.
If all the people around you achieve more than you, then life will be good. You don’t have to believe me. I’ve seen this happen repeatedly.
It doesn’t matter if they are employees, investors, friends, spouses. If you just focus on this one principle in all of your actions then you are a leader.
